In this paper, the weak signal detection under α stable noise is investigated based on bistable vibrational resonance (VR) which is driven by a high frequency signal. On the one hand, the energy of the high frequency drive signal is transferred to the low frequency weak signal when VR occurs; on the other hand, the control of stochastic resonance (SR) is achieved based on VR, which transfers more noise energy into useful signal energy. In addition, considering the requirements of real-time detection, the amplitude and frequency of the high frequency drive signal are optimized by the knowledge-based particle swarm optimization (KPSO), which takes the mean signal-noise-ratio (MSNR) of output as the fitness function, and the property that VR system produces the best resonance effect just when the valid system parameter â(B,Ω) is greater than zero as knowledge. Finally, the parameter compensation is combined to achieve multi-high frequency weak signals detection with a stable noise. Furthermore, the method is applied to the vibration fault diagnosis of a mono-crystalline silicon furnace, and the experiment results show the effectiveness and practicability of the method.

In order to solve the problems with the 6-DOF parallel robot controlled by traditional PID controller, such as slow response, low control accuracy, and poor robustness, this chapter designs a fuzzy PID controller via fuzzy-adaptive PID control algorithm. The fuzzy control rules are designed through the establishment of a membership function based on given language variables. At last, Matlab is employed to simulate the PID controller and the response of ordinary PID controller to the open-loop transfer function. Experiments show that the designed fuzzy PID controller, with the features of fast response, strengthened robustness, high accuracy, and no overshoot, enhances the performance of control of 6-DOF parallel robot. © 2014 Springer Science+Business Media New York.

The paper presents a signal control strategy of urban traffic networks (UTNs), under which states of UTNs can realize asymptotic stable consensus. We first propose a simulation model of UTNs, where the topology of road network is represented by a directed dynamic graph, and the transfer of underlying traffic flows is modeled by the cell transmission model (CTM). Furthermore, under some assumptions, we can obtain a signal control model of UTNs, which is a discrete-time linear time-invariant control system, and then design a state-feedback control law, under which the proposed control system can realize asymptotic stable consensus. At last, we illustrate basic ideas of our methods by an example.

LTD. 100081 China

In this paper, releasing range model of traffic guidance information is formulated based on combinatorial optimization by the correlation analysis of road traffic flow in time and space. As it is hard to get the optimal solution in a limited time through analysis, a greedy algorithm and a simulated annealing (SA) based algorithm are presented to solve the model. Some traffic flow data detected by remote microwave sensors in some road links in Beijing urban expressway are employed to compare the two algorithms. The results show that SA based algorithm has achieved better result even its running time is little longer than the greedy algorithm. Therefore the proposed SA based algorithms can be used to improve the pertinency, validity and automation of releasing traffic guidance information.
